Description of Issue

missing Performance section in Volttron Central UI.

The 'status/cpu' is being published by the platform.agent but not correctly processed in the Volttron Central agent:

2018-09-28 09:53:12,670 (listeneragent-3.2 788) listener.agent INFO: Peer: 'pubsub', Sender: 'platform.agent':, Bus: u'', Topic: 'datalogger/platforms/vcp-Test_Platform_1/status/cpu', Headers: {'max_compatible_version': u'', 'min_compatible_version': '3.0'}, Message: {'percent': {'Readings': 15.2, 'Units': 'double'}, 'times_percent/guest': {'Readings': 0.0, 'Units': 'double'}, 'times_percent/guest_nice': {'Readings': 0.0, 'Units': 'double'}, 'times_percent/idle': {'Readings': 84.8, 'Units': 'double'}, 'times_percent/iowait': {'Readings': 0.8, 'Units': 'double'}, 'times_percent/irq': {'Readings': 0.0, 'Units': 'double'}, 'times_percent/nice': {'Readings': 0.0, 'Units': 'double'}, 'times_percent/softirq': {'Readings': 0.1, 'Units': 'double'}, 'times_percent/steal': {'Readings': 0.0, 'Units': 'double'}, 'times_percent/system': {'Readings': 3.3, 'Units': 'double'}, 'times_percent/user': {'Readings': 11.1, 'Units': 'double'}}

Affected Version

Release 5.1

Expected

Performance section is displayed above 'Building' and 'Agents'.

Actual

Performance section is missing in Volttron Central web UI.

Steps to Reproduce

1) setup a basic Volttron Central enable Volttron system:

$ volttron-cfg

Your VOLTTRON_HOME currently set to: /home/jens/.volttron3

Is this the volttron you are attempting to setup? [Y]: What is the external instance ipv4 address? [tcp://127.0.0.1]: What is the instance port for the vip address? [22916]: Is this instance a volttron central? [N]: y Configuring /home/jens/Projects/volttron/services/core/VolttronCentral

In order for external clients to connect to volttron central or the instance itself, the instance must bind to a tcp address. If testing this can be an internal address such as 127.0.0.1.

Please enter the external ipv4 address for this instance? [http://127.0.0.1]: What is the port for volttron central? [8080]: Enter volttron central admin user name: admin Enter volttron central admin password: Retype password: Installing volttron central Should agent autostart? [N]: y Will this instance be controlled by volttron central? [Y]: y Configuring /home/jens/Projects/volttron/services/core/VolttronCentralPlatform Enter the name of this instance. [tcp://127.0.0.1:22916]: Enter volttron central's web address [http://127.0.0.1]: What is the port for volttron central? [8080]: Should agent autostart? [N]: y Would you like to install a platform historian? [N]: y Configuring /home/jens/Projects/volttron/services/core/SQLHistorian Should agent autostart? [N]: y Would you like to install a master driver? [N]: y Configuring /home/jens/Projects/volttron/services/core/MasterDriverAgent Install a fake device on the master driver? [N]: y Should agent autostart? [N]: y Would you like to install a listener agent? [N]: y Configuring examples/ListenerAgent Should agent autostart? [N]: y Finished configuration

You can now start the volttron instance.

If you need to change the instance configuration you can edit the config file at /home/jens/.volttron3/config

2) Point browser to:

http://127.0.0.1:8080/vc/index.html

3) Login/Password: admin/admin

4) Expand platform: tcp://127.0.0.1:22916

-> You will see the 'Building' and 'Agents' section but not the 'Performance' section

Is this the correct topic to subscribe to:

platforms//datalogger/platform/status

This is the topic currently being send:

datalogger/platforms/vcp-Test_Platform_1/status

Could this be the problem?

Thanks @jens18 I will take a look at it

jens18 commented 5 years ago

Generating a graph for a 'Performance' metric (for example: times_percent / user) works with the 'Add Chart' button (upper right corner).

The 'list of available' Performance metrics on the left site (under the platform) entry is missing.
